19 * TEST IDENTIFIER : timer_create03
20 *
21 * EXECUTED BY : anyone
22 *
23 * TEST TITLE : Basic test for timer_create(2)
24 *
25 * TEST CASE TOTAL : 3
26 *
27 * AUTHOR : Aniruddha Marathe <aniruddha.marathe@wipro.com>
28 *
29 * SIGNALS
30 * Uses SIGUSR1 to pause before test if option set.
31 * (See the parse_opts(3) man page).
32 *
33 * DESCRIPTION
34 * This is a Phase I test for the timer_create(2) system call.
35 * It is intended to provide a limited exposure of the system call.
36 *
37 * Setup:
38 * Setup signal handling.
39 * Pause for SIGUSR1 if option specified.
40 *
41 * Test:
42 * Loop if the proper options are given.
43 * Execute system call with different notification types for
44 * clock ID CLOCK_MONOTONIC
45 * Check return code, if system call failed (return=-1)
46 * Log the errno and Issue a FAIL message.
47 * Otherwise, Issue a PASS message.
48 *
49 * Cleanup:
50 * Print errno log and/or timing stats if options given
51 *
52 * USAGE: <for command-line>
53 * timer_create03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
54 * where:
55 * -c n : Run n copies simultaneously.
56 * -e : Turn on errno logging.
57 * -i n : Execute test n times.
58 * -I x : Execute test for x seconds.
59 * -p : Pause for SIGUSR1 before starting
60 * -P x : Pause for x seconds between iterations.
61 * -t : Turn on syscall timing.
62 *
63 *RESTRICTIONS:
64 * None
